The
module presents a model of human interaction with machines, computers,
or other systems and potential environmental influences on that
interaction. This model conceptually divides a system into
a "human-side" and a "machine-side" to illustrate
and describe these interactions. Understanding the comparative
strengths and weaknesses of the human versus the machine side of
a system is crucial to the design of systems that capitalize on
human capabilities and compensate for human limitations.
